CHURN.

SPECIFICATION forming part of Letters Patent No. 328,696, dated October 20, 1885.

Serial No. 171, 0827 (No model.)

To aZZ whom, it may concern Be it known that I, THOMAS MAOHAN, of Belle Isle, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Chorus, of which the following, taken in connection with the accompanying drawings, isa i'ull,clear, and exact description.

In said drawings, Figure l is a longitudinal section of my improved churn, taken on line 00 00, Fig. 2. Fig. 2 is a vertical transverse section on line y 3 Fig. l; and Fig. 3 is a vertical section on line .2, Fig. 1, showing the detachable connection of the shaft of the cylinder to the tank of the churn.

Similar letters of reference indicate corresponding parts.

This invention relates to the class of churns which have the dashers hinged to a rotary cylinder, and also has reference to the classin which the said cylinder is hollow for the re ception of warm or cold water.

My invention consists in an improved construction and combination of the constituent parts of the churn, whereby the same is rendered more efficient in its operation.

cream to be churned. G is a hollow cylinder pivoted horizontally in said tank by means of hollow shafts c and c, journaled in suitable hearings in opposite sides of the tank. The shaft 0 is extended longitudinally through the cylinder, and is perforated inside thereof and rigidly secured to the cylinder-heads. It terminates at one end on the cylinder-head h, and projects with its opposite end through the side of the tank, as shown in Fig. 1 of the drawings. The other shaft, 0, is screwed into the cylinder-head h, and thus detachably connected thereto. At the outside of the tank the shaft 0 is provided with a hollow crankextension, 0, to which is connected a handle, h, by which to rotate the cylinder 0. The shaft 0 is provided at the exterior of the tank with a collar, 2, and is detachably secured to the tank by means of a plate, Z, provided with slots on m standing radially to the shaft 0, through which slots the attaching-screws n a pass and enter the side of the tank. The collar 2', abutting against the exterior of the tank, and the plate I, pressing against the outer side of the collar 2', serve to restrain the shaft from moving endwise.

By loosening the screwsn n and slipping the plate Z away from the shaft 0 the latter is released to allow it to be withdrawn from the tank after said shaft has been unscrewed from the cylinder, and when this is effected and the pipe f, hereinafter described, is removed from the shaft 0 at the opposite end of the tank, the cylinder can be removed through the top of the tank, which latter is provided with a removable cover, A.

6 represents a ventiduct arranged inside the hollow shaft 0, and terminating with lateral branches 6 a, extending through the side i of the shaft, respectively, at the inside of the cylinder and at the outside of the tank, as shown in Fig. l of the drawings, the inner branch. 0, pointing in the same direction as the hollow crank c and extending to within a short distance from the concave side of the cylinder, so that when turning the crank 0 into an erect position and introducing water into the same the air will escape from the upper part of the interior of the cylinder through the ventiduct c. A denotes the tank or receptacle for the Onto the outer end of the hollow shaft 0 screws a pipe or elbow of a pipe, f, for the discharge of the water from the shaft 0. Suitable stoppers, 88, are applied to the pipcf and crankextensions c to retain the water in the hollow shafts and cylinder when desired. The pipe f embraces the end of the shaft 0, and when screwed onto the same it covers the outer end of the ventiduct c to prevent the escape of water through the latter. Du ring the opera tion of charging the cylinder with water the pipe f is to be partly unscrewed, so as to expose the outer end of the ventiduct and allow the air to escape therefrom. After the cylinder has been filled,the pipef is to be further screwed onto the shaft 0 to cover the Outer end of the ventiduct, as shown in Fig. 1 of the drawings.

The cylinder is provided in its side with an opening and a removable plug in said opening. By removing the latter and turning the cylinder to bring the opening to the bottom, all the water can be drawn from the cylinder.

a (0 represent dashers or heaters extending lengthwise the cylinder 0, and hinged thereon by arms a, rigidly attached to the dashers a and pivoted on the cylinder eccentrically in relation to the axis of said cylinder. The movementof the dasher a on the cylinderO is lim- 5 ited in one direction by the encounter of said dasher with the side of the cylinder, and the movement of the dashers in the opposite direction is limited by a brace, I), attached to the dasher and constituting a knuckle or shoulder which collides with the side of the cylinder.

In revolving the cylinder 0 in the direction indicated by the arrow in full lines in Fig. 2 of the drawings, the resistance of the cream I 5 inside of the tank A crowds the dashers until they are arrested by the abutment of the brace or knuckle 1) against the cylinder, which sus taius the dashers nearly or quite radially in relation to the cylinder, and this holds them in proper position to agitate and churn the cream. 1

By reversing the motion of the cylinder, as represented by the dotted arrows in Fig. 2 of the drawings, the dashers are allowed to yield to the resistance of the cream and fall toward the cylinder, where they are sustained by the encounter ofthe dasher with the cylinder, and in this position the dashers trail through the cream and thereby serve to gather the globules of butter.

' Having described my invention. what I claim as new, and desire to secure by Letters Patent, is-

1. In combination with the tank A, the cylinder O, pivoted horizontally in said tank and provided with a water inlet and outlet, the dashers a' at, extending lengthwise the said cylinder and hinged thereon, and knuckles or shoulders on the joints of the dashers to limit 0 their movement, substantially as set forth and shown.

2. In combination with the tank A, the cylinder O, pivoted horizontally in said tank and provided with a water-inlet and water-outlet,

5 respectively, at opposite ends, the dashers a a,

extending lengthwise the cylinder and hinged thereon eccentrically in relation to the axis of said cylinder to limit the motion ofsaid dashers in one direction, and knuckles or shoulders on the joints of the dashers to limit their s movement in the opposite direction, substan tially as described and shown.

3. The combination of the tank A, the ho] zontal cylinder 0, having the hollow shaft projecting from one end of the cylinder thron we the side of the tank and terminating on the head h of the opposite end of the cylinder an perforated inside thereof, and the hollow shatv-1. c, detachably connected to the cylinder-head I h and extending through the side of the tank 6c" and provided with the hollow crank-extension c, and stoppers for closing the said hollow shafts, substantially as described and shown.

4. In combination with the tank A, the horizontal cylinder 0, the hollow shaft 0, projecting through the side of the tank, the ventiduct 6, arranged inside of the shaft 0 and terminati ng with lateral branches extending through the side of the shaft, respectively,at the inside of the cylinder and at the outside of the tank,

substantially as described and shown.

5. In combination with the tank A, the horizontal cylinder 0, the hollow shaft 0, projecting through the side of the tank, the ventiduct 6, arranged inside of the shaft 0 and termiuating with lateral branches extending through the side of the shaft, respectively,at the inside of the cylinder and at the outside of the tank, and the pipef, screwed onto the outer end of the shaft 0, covering the outer end of the ven- 8o tiduct e, substantially as described and shown.

In testimony whereoflhave hereunto signed my name, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga and State of New York, this 15th day of June, 1885.
